Definitions

  • the present invention relates to a floor covering for a passenger conveyor such as an escalator or a moving walkway.
  • the invention also relates to a passenger conveyor with such a floor cover.
  • Passenger conveyor devices such as escalators (sometimes also referred to as escalators) or moving walks are used to convey people along an inclined or horizontal path.
  • escalators sometimes also referred to as escalators
  • moving walks are used to convey people along an inclined or horizontal path.
  • an underfloor space accommodates, for example, technical equipment of the passenger conveyor such as its drive unit, control unit, etc.
  • this underfloor space is usually covered with a floor cover that can be walked on.
  • the floor cover is usually designed in such a way that it can be removed or opened temporarily, for example, by maintenance personnel.
  • EP 0 885 832 B1 describes a floor cover for a passenger conveyor which can be opened.
  • floor covers are provided with transverse grooves on their upwardly directed tread to prevent the risk of slipping, objects can get stuck in the transverse grooves. As a result, there is the possibility that in certain operating situations the floor cover could be unintentionally lifted. For example, persons whose shoe gets caught in the floor covering with a heel could inadvertently exert forces on the floor covering in such a way that it unintentionally lifts or even opens.
  • a floor covering of a passenger conveyor device for covering an underfloor space is described.
  • the base cover has at least a first and a second plate-shaped cover element arranged one behind the other and at least one coupling element.
  • Each cover element has an upwardly directed step surface and a first and a second end surface at opposite ends.
  • a first and a second cover element are arranged one behind the other in such a way that a first end face of the first cover element lies opposite a second end face of the second cover element.
  • the coupling element is interposed between the first end face of the first cover element and the second end face of the second cover element.
  • the coupling element has at least one coupling area with a coupling pivot point. The coupling area is designed to couple the first cover element to the second cover element in such a way that the first cover element and the second cover element are connected to one another in an upwardly directed tension and can be angled relative to one another around the coupling pivot point.
  • At least one resilient return area is also formed on the coupling element, which is arranged vertically below the coupling pivot point between the first cover element and the second cover element.
  • This resilient restoring area causes a restoring force which acts on the adjoining end faces and is deflected by the coupling pivot point as soon as one of the cover elements is lifted upwards from its position in the desired configuration.
  • the deflected restoring force is directed in such a way that the raised cover element is subjected to force towards its position in the desired configuration becomes.
  • the restoring force generated by the restoring area and deflected by the coupling pivot point counteracts the lifting force acting on one of the cover elements.
  • the terms “up” and “down” or “up” and “down” relate to the position and orientation of the components of an operational passenger conveyor.
  • An upward force on the cover element therefore counteracts gravity at least in part, while a downward force is directed in the direction of gravity or has a force vector which points in the direction of gravity.
  • a passenger conveyor which has a conveyor unit for conveying people along a travel path, an underfloor space adjacent to the travel path and a floor cover according to an embodiment of the first aspect of the invention which covers the underfloor space.
  • the entire floor cover is composed of the multiple cover elements in a segment-like manner, with the individual cover elements being able to be raised and, if necessary, opened up in order to be able to open the floor cover easily.
  • the cover elements are plate-shaped, that is to say essentially two-dimensional, that is to say the dimensions of the cover elements within a plane of extent are significantly greater than a thickness of the cover elements transverse to the plane of extent.
  • Each cover element forms a step surface on its upper side which a person can walk over and which can be profiled, for example, to reduce the risk of slipping, for example by means of transverse grooves provided therein.
  • the Cover elements can generally be flat or slightly curved.
  • the cover elements should be sufficiently stable and stable to be able to withstand the forces exerted by people running over them.
  • the cover elements can for example consist of metal, in particular aluminum, and can be produced for example by extrusion.
  • the cover elements are arranged one behind the other in such a way that their tread surfaces adjoin one another, with respective end faces of adjacent cover elements lying opposite one another.
  • the target configuration corresponds to that arrangement of the cover elements in which they completely cover the underfloor space.
  • the cover elements were usually coupled to one another so as to be able to withstand tensile loads, at least slightly, by coupling elements arranged between them. If necessary, the coupling elements were also designed to prevent adjacent metallic cover elements from rubbing directly against one another and thereby generating creaking noises, for example.
  • the depth of the transverse grooves had to be limited so that nothing can get stuck in the transverse grooves. As a result, the individual cover elements cannot be lifted by exerting an upward force which overcomes the gravitation acting on them.
  • the limitation of the transverse groove depth reduces their effectiveness with regard to the risk of slipping, in particular at locations where a high level of contamination is to be expected.
  • the coupling element is provided with at least one so-called reset area.
  • This restoring area is designed to bring about, in addition to the gravitational force acting on a cover element, a restoring force which is deflected by the coupling pivot point and directed in such a way that it counteracts a lifting of the cover element.
  • the restoring force is brought about as soon as an attempt is made to lift the cover element.
  • the restoring force thus acts in such a way that when an attempt is made to lift a cover element of the base cover, this cover element is acted upon by force in such a way that it is loaded back into the predetermined target configuration. Due to the resilient configuration of the reset area, the reset force is produced in an elastically resilient manner.
  • the coupling element and the cover elements are designed in such a way that the reset area is arranged vertically below the coupling area or the coupling pivot point, on the one hand on the first end face of the first cover element and on the other hand on the second end face of the second cover element.
  • the cover elements on their opposite end faces and the coupling element arranged between these end faces are designed in such a way that the restoring area of the coupling element is located below its coupling area, i.e. further away from the upwardly directed step surface and the coupling pivot point arranged below the step surface .
  • the reset area rests on its opposite sides against the respective end faces of the two opposite cover elements and is supported on them.
  • the two cover elements tend to tilt towards each other in such a way that their end faces move away from each other above the coupling pivot point, ie near the step surface, and one below the other below the coupling pivot point want to move.
  • One such Tilting counteracts the reset area provided below the coupling pivot point of the coupling element. This ultimately counteracts any lifting of the cover element.
  • the coupling element is formed with polymer material.
  • the coupling element can consist of polymer material.
  • the coupling element can be produced simply and inexpensively, for example by injection molding processes.
  • the coupling element is formed with polypropylene or consists of polypropylene. If necessary, other polymer materials, additives or the like can be added to the polypropylene in order to be able to vary its properties, such as its hardness and / or strength, depending on the area.
  • the coupling element is designed in one piece.
  • the coupling element can be provided as a single component and can integrate and encompass both the coupling area and the reset area.
  • the coupling element can thus be produced inexpensively and simply, for example by injection molding. Storage, logistics and / or assembly costs can also be reduced.
  • the coupling element in the restoring area is formed with a material with a Shore A hardness of more than 65, preferably more than 70 and more preferably more than 75. At least in the reset area, the coupling element is therefore preferably relatively hard or firm. This allows a strong restoring force to be brought about without significant deformations occurring.
  • the coupling element is formed in the coupling area with a material with a Shore A hardness of less than 65, preferably less than 60 and more preferably less than 50.
  • the coupling element can thus preferably be relatively soft.
  • the coupling element can be made with a softer material in its coupling area be designed as in its reset area. The coupling area can thus be easily deformed locally, for example in order to be able to latch it into one of the cover elements.
  • the base cover also has a damping element which is interposed between the first end face of the first cover element and the second end face of the second cover element in a region in which the first and the second end face are minimally spaced from one another when the target configuration of the base cover is present .
  • a damping element can be provided between two adjacent cover elements.
  • This damping element can, for example, absorb longitudinal forces that act between these cover elements.
  • the damping element can prevent, for example, metal surfaces of the two adjacent cover elements from resting directly against one another and creaking noises and / or wear occurring when these metal surfaces rub against one another.
  • the damping element is preferably provided at a position at which the opposing end faces of the two adjacent cover elements are minimally spaced from one another, that is, a gap between the adjacent cover elements has minimal dimensions. As a result, the damping element can be made relatively thin.
  • the damping element is made with a material that has a higher hardness than a material with which the coupling element is formed in its restoring region. Due to its high hardness, the damping element can withstand high compressive forces, such as can occur between the cover elements, for example due to thermally induced dimensional changes.
  • the hardness of the material used for the damping element can be at least 5%, preferably at least 10% or at least 20% higher than the hardness of the material used for the restoring area of the coupling element or the hardness of this material by, for example, at least 5, preferably at least 10, Shore A hardness levels exceed.
  • the damping element is formed with polyamide or consists of polyamide.
  • Polyamide is a relatively hard, resistant polymer material that can be manufactured and processed easily and inexpensively.
  • the damping element is attached to the coupling element.
  • the damping element can be attached directly to the coupling element. A unit of damping element and coupling element can thus be produced, stored, handled and ultimately installed together.
  • the damping element is preferably designed in one piece with the coupling element. That is to say, the damping element can be an integral part of the coupling element.
  • the damping element can project from the coupling area of the coupling element, for example.
  • the damping element which is preferably made of polymer material, can, for example, be integrally molded onto a region of the coupling element. It can, but does not necessarily need, that the damping element consist of a different polymer material than areas of the coupling element.
  • the damping element can consist of polyamide, whereas the coupling area and the restoring area of the coupling element are preferably made of polypropylene.
  • Fig. 1 shows a passenger conveyor 1 in the form of an escalator.
  • a conveyor unit 2 can transport people along a travel path 4.
  • An underfloor space 3 is provided at an upper and a lower end of the escalator in which, for example, a drive, a controller, etc. (not shown) are accommodated.
  • Each underfloor space 3 is covered with a floor cover 5, so that people can walk over a tread 7 formed by this and enter or leave the escalator.
  • Fig. 2 shows an enlarged sectional view through a base cover 5.
  • the base cover 5 is composed of several plate-shaped cover elements 9.
  • the cover elements 9 are arranged one behind the other in a common plane, with first and second end faces 11, 13 of adjacent cover elements 9 each facing one another.
  • the foremost cover element 9 (on the far left in the figure) is itself tapered and adjoins a comb plate 15.
  • a support structure 16 supports the base cover 5.
  • Fig. 3 shows a sectional view through two cover elements 9, coupled to one another, of a conventional floor covering as an enlargement of area “A” Fig. 2 .
  • the two cover elements 9 adjoin one another along a boundary line 23 with their first and second end faces 11, 13.
  • a coupling element 17 engages on the one hand with a nose 18 in a cavity 19 of the first cover element 9 and is positively locked in this.
  • a projection 21 on the opposite second cover element 9 engages from an opposite side into the ⁇ -shaped nose 18 of the coupling element 17.
  • the two cover elements 9 are connected to one another so that they can be subjected to tensile loads via the coupling element 17. In this case, however, the cover elements 9 can be tilted relative to one another if they are raised at one point. This is used in particular to be able to fold away the cover elements 9, for example in order to be able to locally remove the floor cover 5 during a maintenance process and to be able to expose the underfloor space 3 below.
  • Fig. 4 is shown by way of example how a shoe 25 hooks with its heel in transverse grooves of a cover element 9 on its tread surface 7 and then a force F S is exerted on the cover element 9 by the person wearing the shoe 25. Since this force F S conventionally only counteracts the gravitational force F G of the cover element 9, it can happen that both the cover element 9, in which the shoe 25 is hooked, and an adjoining cover element 9 are lifted locally.
  • two cover elements 9 to be coupled to one another with a specially developed coupling element 17, in which when one of the cover elements 9 is raised, a restoring force is generated in a targeted manner, which loads the raised cover element 9 back to the desired configuration.
  • a coupling element 17 according to the invention coupling two adjacent cover elements 9 is shown as an example.
  • the coupling element 17 is interposed between the opposite end faces 11, 13 of the two cover elements 9.
  • the coupling element 17 has both a coupling area 27 and a reset area 29.
  • the coupling area 27 and the reset area 29 are integrated in a single component forming the coupling element 17.
  • the coupling area 27 can be designed similarly to that in FIG Fig. 3 conventional coupling element 17 shown.
  • a nose 18 can engage undercutting in a cavity 19 of the first cover element 9 and be locked therein in a form-fitting manner.
  • a projection 21 protruding from the second cover element 9 on its second end face 13 can be pushed into the nose 18 from the rear, optionally with a friction fit.
  • the coupling area 27 can connect the two cover elements 9 to one another so that they can be subjected to an upward tension.
  • the coupling area 27 is designed in such a way that the two cover elements 9 can be tilted relative to one another. In order to make this possible, there is a sufficient local clearance between the projection 21 and the coupling element 17 in the form of a coupling pivot point 20. In other words, this means that two cover elements 9 arranged next to one another are coupled in such a way that the first cover element 9 and the second cover element 9 are connected to one another in an upwardly directed tension and can be bent relative to one another about the coup
  • the reset area 29 is integrally formed on the coupling element 17 vertically below the coupling area 27 or the coupling pivot point 20.
  • the reset area 29 is adapted to the geometry of the two end faces 11, 13 of the opposing cover elements 9 in such a way that it is on one side on the first end face 11 of the first cover element 9 and on the opposite side on the second end face 13 of the second cover element 9 is supported.
  • a protruding area 31 is formed on the first end face 11, on which the restoring area 29 can be supported.
  • An opposite end of the reset region 29 rests on the second end face 13 and is supported there.
  • the coupling area 27 may be advantageous to design the coupling area 27 with a softer material than the restoring area 29.
  • the coupling area 27 can, for example, have a Shore A hardness of 50 to 60, whereas the restoring area 29 has a Shore A hardness of 70 up to 75 can be trained.
  • the nose 18 can be pushed into the cavity 19 and latched more easily, and the projection 21 can also be pushed better into the nose 18 from behind.
  • the harder and thus stronger restoring area 29 can ensure more stable support and a higher restoring force between the two cover elements 9.
  • the entire coupling element 17 can be formed with a polymer material such as polypropylene or at least partially consist of polypropylene. It can be advantageous to make the different areas differently hard, for example by adding additives.
  • a damping element 35 is interposed between the two cover elements 9.
  • the damping element 35 is temporarily stored at a position between the opposite end faces 11, 13 of the two cover elements 9 at which they are minimally spaced from one another. In the example shown, this is in an area directly adjacent to the treads 7.
  • the damping element 35 is intended to prevent areas of the cover elements 9, which are typically made of metal, from directly adjoining one another and thus rubbing against one another when the two cover elements 9 move relative to one another and can generate annoying noises. If necessary, the damping element 35 can also serve as a sealing lip between the adjacent cover elements 9 in the area of the boundary line 23.

  • the coupling element 17 can also be designed in one piece in this case and can be produced, for example, by injection molding, it can also be possible in such a configuration to design the area of the damping element 35 with a harder material than the coupling area 27 and / or the reset area 29. In particular, different materials can also be used in a common component. Using modern injection molding processes, for example, the coupling and the Restoring area 27, 29 can be formed with polypropylene, whereas the area of the damping element 35 can be formed with harder polyamide.
